Hello sirs,
Thanks for your valuable reply. I am presently doing feasibility study regarding usage of PE pipe in our project . We are preferring to use PE pipe for underground services because of supports required for above ground service and high thermal coefficient which requires large expansion loops . But the limitation of the PE pipe even in underground service is if we are going for higher size diameter than pressure withstandability becomes lesser and service life also becomes lesser.
My query is also for joining techniques. Generally for underground usage we prefer not to have bolted connection. For our purpose electrofusion welding of PE pipe is feasible. But it also has size limitation. So pls if any of you had dealt with PE 100 pipe than can you suggest any alternative for this joining technique.
Regards,
Padmaja.

Hi All,
I know of DN2000 pipe being manufactured in Europe. It was extruded in 1000m lengths into the harbour. Yes the harbour was used as the cooling bath. Dont know if the "greenies" would let that happen today. Anyway the pipe was loded onto a train and transported to Poland from Germany by train in 1000m lengths. it was then laid with just the 7 butt welds.
I have seen the video of the exercise; so as Herculean task as it seems it did happen. I think the pipe manufacturer was Borealis. So you are not limited to what is produced in your country. If you need large diameter PE it could be floated across oceans if that is what your heart desires.

Have you thought of contacting your local supplier/manufacture
representative for this information? I am sure that if you intend to use
this product on a project it will have to be procured at some point. It is
of little worth having piping sizes and information supplied by others if
for some reason it is not available at a semi local level and may need to
be
imported. This is especially so if project deadlines are to be met.
I hope this assists you in your quest for information.
Cheers,
Robin
